ASA UWF300 f1.3 + DDM100 + wedge
One of the fastest telescopes of the world!
The UWF300_1 package combines the highly-corrected 300mm f1.3 UWF OTA with our outstanding ASA DDM100 mount. This groundbreaking optical design is ideal for short exposure, high SNR wide field surveys.
The main mirror works with absolute encoder feedback and can be collimated fully electronic for an easy and fast remote collimation.
The DDM100 Direct Drive mount is a precision platform ready for fully automated imaging.
